Naphthalene, the simplest bicyclic aromatic ring, is conventionally derived from coal tar. It is a white solid material with strong pungent odour. Naphthalene was first discovered by Scottish chemist, Alexzander garden in 1819. Michael Faraday first reported its molecular formula (C 10 H 8) in 1826 [1]. Conventionally, naphthalene is ...

The toxicity of naphthalene has been well documented and cataractogenic activity has been reported in laboratory animals [4,5]. Naphthalene binds covalently to molecules in liver, kidney and lung tissues, thereby enhancing its toxicity; it is also an inhibitor of mitochondrial respiration [9]. Acute naphthalene poisoning in humans can lead to ...

Feb 3, 2011 · Naphthalene conversion (naphthalene hydrogenated to tetralin, octalins and decalins) varied from 4 to 96%. This corresponds to a naphthalene hydrogenation rate of 1-24×10 3 mol/(kg cat s). An additional experiment carried out with very low catalyst loading led to a low naphthalene conversion and only tetralin as product.

Jan 1, 2025 · Naphthalene is a two fused benzene ring polycyclic aromatic hydrocarbon. Naphthalene was initially registered with the U.S. Department of Agriculture (USDA) as a pesticide in 1948. The United States Environmental Protection Agency (EPA) issued a registration standard for naphthalene in 1981, and the substance was reregistered by the agency in 2008.

Jan 1, 2019 · Naphthalene, the simplest bicyclic aromatic ring, is conventionally derived from coal tar. It is a white solid material with strong pungent odour.

Naphthalene (91-20-3) is a component of crude oil and is found in petroleum-derived fuels and consumer products. The most common use of naphthalene in consumer products is in the production of mothballs. Naphthalene ingestion can result in acute as well as delayed toxicity. The primary target organs of toxicity are the blood and the eyes.

Naphthalene. Heriberto Robles, in Encyclopedia of Toxicology (Second Edition), 2005. Uses. Naphthalene is commonly used in the manufacture of dyes, resins, and mothballs and may also be found in association with coal tar production and in wood preservatives.

Mar 1, 2024 · Naphthalene, the most abundant polycyclic aromatic hydrocarbon in the atmosphere, significantly influences OH consumption and secondary organic aerosol (SOA) formation. Naphthoquinone (NQ) is a significant contributor to ring-retaining SOA from naphthalene degradation, impacting the redox properties and toxicity of ambient particles.

Dec 1, 2023 · Naphthalene (NAP), 1-naphthol (1-NAP) and 2-naphthol (2-NAP) are the thermal decomposition products of naphthalene sulfonates making them potentially new geothermal reservoir permeability tracers, however, to date, no sensitive and fast detection method for these compounds has been developed.

Jan 1, 2019 · Naphthalene, an organic compound with formula C 10 H 8, is also known as naphthene, naphthalin, camphor tar, and white tar. It is an essential compound of coal tar [27]. The structure of naphthalene consists of a fused pair of benzene rings. It is the simplest polycyclic aromatic hydrocarbon and is a white crystalline solid.
